Question

Which pair of triangles can be proven congruent by the HL theorem?

2 right triangles have congruent hypotenuses.
2 triangles have one congruent angle and 2 congruent sides.
2 right triangles have congruent hypotenuses and another congruent side.
2 triangles have 3 congruent sides.

Answer 1

C 2 right triangles have congruent hypotenuses and another congruent side

Step-by-step explanation:

The HL theorem applies only to right triangles. In order for it to apply, the hypotenuse (H) must be congruent, and one legs (L) must be congruent from one triangle to the other.

If you recognize that HL is an abbreviation for Hypotenuse-Leg, then the wording of your answer choices tells you which is correct.
